The malignant or benign nature of a salivary gland (SG) tumor can be predicted with reasonably high accuracy by imaging. There is some overlap between the imaging findings of benign and malignant tumors, particularly for low-grade malignancies, and tissue diagnosis remains necessary for definitive diagnosis. Magnetic resonance imaging is the modality of choice for the evaluation of salivary neoplasms, as it allows for delineation of local infiltration, perineural spread and intracranial extension. This review will focus on the advanced imaging techniques that help to characterize SG tumors. A brief overview of the conventional imaging features of SG neoplasms is necessary before a discussion of the advanced imaging methods.
